Rick Leventhal reported today on the amazing story of a legally blind skier who's getting ready to compete at the Paralympic Games in Sochi. Staci Mannella, a native of New Jersey, is the youngest member of the U.S. team.

Mannella can only see a few feet in front of her as she races down the mountain at speeds up to 55 mph.

Mannella suffers from achromatopsia, a a non-progressive and hereditary eye disorder that leads to decreased vision, light sensitivity, and the absence of color vision.

In the report above, we learn how Mannella and her guide, who wears a bright yellow jacket, are able to compete. The pair will try to win gold in the slalom and giant slalom events next week.
